摘　　要：跟踪调查浅位缠泥土上种植小麦常规施肥、测土配方施肥2种方式下氮肥、磷肥和钾肥的利用率现状,为控制化肥施用总量、优化施肥结构、科学运筹肥料、改进施肥方式提供科学依据。本试验设2个试验区,分别为农户习惯施肥种植区和配方施肥示范区。农户习惯施肥种植区设置常规区、不施氮区、不施磷区、不施钾区4个处理;配方施肥示范区设置配方区、不施氮区、不施磷区、不施钾区4个处理。小区面积设置为30 m^2。结果表明,浅位缠泥土上种植小麦,常规施氮、磷、钾,化肥利用率分别为31.69%、16.80%、32.00%;配方施氮、磷、钾,化肥利用率分别为39.79%、25.75%、40.60%。因此,配方施肥方式可明显提高肥料利用率。This research investigated the current utilization rates of nitrogen,phosphate,and potassium fertilizers in the shallow bound soil of a wheat field under the conventional fertilization mode and the soil testing and formulated fertilization mode.It can establish a scientific basis for effectively controlling the total amount of applied fertilizers,optimizing the fertilization structure and pattern,and improving the mode of fertilization.The trial involved two sets of treatments:Set 1 was under the farmers’conventional fertilization mode,and Set 2 was under the soil testing and formulated fertilization mode.Set 1 consisted of four treatments:conventional fertilization treatment,the one without a nitrogen fertilizer,the one without a phosphorus fertilizer,and the one without a potassium fertilizer.Set 2 also comprised four treatments:the treatment with formulated fertilization,the one without a nitrogen fertilizer,the one without a phosphorus fertilizer,and the one without a potassium fertilizer.Each treatment was 30 m^2 in area.As a result,the utilization rates of nitrogen,phosphate,and potassium fertilizers in the shallow bound soil with wheat planted were 31.69%,16.80%,and 32.00%,respectively,under the conventional fertilization mode.By comparison,the corresponding rates under the formulated fertilization mode were 39.79%,25.75%,and 40.60%,respectively.Hence,the formulated fertilization mode significantly improved the utilization rates of all the three fertilizers.
